The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Ichthyoplankton density and plankton displacement volume data collected using SEA-GEAR plankton ring nets on the NSF RAPID Plankton Cruises in the Northwestern Gulf of Mexico in 2017-2018 (NCEI Accession 0291406) |
| Abstract: | This dataset contains biological, physical, and survey - biological data collected on R/V Pelican and R/V Point Sur during cruises PE18-18, PE18-21, and PS1813 from 2017-10-30 to 2018-03-23. These data include abundance, depth, and depth_bottom. The instruments used to collect these data include Mechanical Flowmeter, Microscope - Optical, and Ring Net. These data were collected by Astrid Schnetzer of North Carolina State University, Simon Geist of Texas A&M, Corpus Christi, and Beth Stauffer and Kelly L. Robinson of University of Louisiana at Lafayette as part of the "Collaborative Research: RAPID-HARVEY: Response of plankton assemblages and trophodynamics to a historic, hurricane-induced floodwater plume in a subtropical, pelagic environment (RAPID Plankton)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-12-09. The following is the text of the dataset description provided by BCO-DMO: Ichthyoplankton density and plankton displacement volume data collected using SEA-GEAR plankton ring nets on the NSF RAPID Plankton Cruises in the Northwestern Gulf of Mexico in 2017-2018 Dataset Description: Acquisition Description: The Ring Plankton Net was deployed using the same procedures reported for the NOAA Bongo Plankton Net in the "NOAA SEAMAP Field Operations Manual for collection of data, Chapter V., National Marine Fisheries Service and Gulf States Marine Fisheries Commission, October 2001, Revision No.4." Target Fishing Depth as much of the water column as possible stopping 2-4m above the bottom at bottom depths 200m; ship speed 1.5-2.0 knots; target wire angle of 45°; winch speeds during pay out and retrieving according to Chapter V., Table A. The net was deployed over the side. Nets were rinsed and processed on board. A subset of larval fish was picked on board and frozen at ultra-low temperatures in liquid nitrogen and kept in an on-board Ultra Low Temperature Freezer, transported using a Dry Shipper to Texas A&M University Corpus Christi and stored in an ULT until further processing. The remainder of the sample was preserved in 200 proof Ethanol (ETOH) according to NOAA SEAMAP Operations Manual upon retrieval of nets. After 24 hours, ETOH was exchanged with fresh ETOH. ETOH Plankton samples were stored in 1000ml plastic jars until processing in the Geist Early Life History Research Laboratory at Texas A&M University Corpus Christi during 2017 and 2020. Total Zooplankton Displacement Volume was determined using a calibrated 1000ml measuring cylinder by subtracting the volume of ethanol without sample from the volume of ethanol with sample. The plankton sample was separated from ethanol using a concentrator sieve with a mesh size |
